OKX Adjusts Minimum Price Precision for Spot, Margin, and Perpetual Swap Trading

To enhance market liquidity and improve the overall trading experience, OKX will adjust the minimum price precision (tick size) for a selection of spot, margin, and perpetual swap trading pairs. This update is scheduled to take place between 2:00 PM and 6:00 PM (UTC+8) on July 9, 2025.

During the adjustment window, trading for the affected pairs will continue uninterrupted. The modifications are designed to create a more efficient and fluid market environment for all users.

What is Minimum Price Precision?

Minimum price precision, often referred to as 'tick size,' is the smallest allowable increment by which the price of a trading pair can move. For example, if a token has a tick size of 0.0001, its price can change from 1.0000 to 1.0001, but not to 1.00005.

Exchanges optimize these values to balance market liquidity with precise price discovery. A smaller tick size allows for finer price gradations, while a larger one can help consolidate liquidity at specific price points.

The following tables outline the specific trading pairs and their respective tick size changes. Adjustments for leveraged tokens in the margin market will be synchronized with their corresponding spot pairs.

How This Affects Your Trading Strategy

Traders, particularly those employing high-frequency or algorithmic strategies, should take note of these changes. A finer price precision can lead to more competitive order books and potentially narrower bid-ask spreads.

It is crucial to review and, if necessary, update any open orders, trading bots, or algorithms that involve these specific pairs to ensure they comply with the new precision rules after the update. This proactive measure will help avoid potential order placement errors.

The Goal: A Better Trading Experience

These ongoing optimizations are part of a broader commitment to providing a top-tier trading environment. By refining parameters like minimum price precision, the exchange aims to:

• Improve Market Liquidity: Encouraging more orders to be placed at a greater variety of price points.
• Enhance Price Discovery: Allowing asset prices to be determined more accurately by market forces.
• Reduce Slippage: Potentially minimizing the difference between the expected price of a trade and the price at which it is executed.

We appreciate your understanding and encourage you to adapt your strategies accordingly for a seamless transition. OKX remains dedicated to offering superior products and services.

Frequently Asked Questions

Q: Will my existing open orders be canceled during the update?
A: No, the adjustment process will not cancel any existing open orders. However, after the new precision is in effect, any new orders placed must adhere to the updated tick size.

Q: What happens if I try to place an order with the old price precision after the update?
A: The trading system will reject the order. You will receive an error notification prompting you to enter a price that matches the new, required minimum precision increment.

Q: Does a smaller tick size mean the price can move more volatility?
A: Not directly. Volatility is driven by market activity and news. A smaller tick size allows the price to be quoted more precisely, but it does not inherently cause larger price swings.

Q: Are only the pairs listed in the table affected?
A: Yes, the changes are specific to the trading pairs detailed in the announcement. All other pairs will maintain their current minimum price precision settings.

Q: How can I stay informed about future similar updates?
A: It is always a good practice to regularly check the official announcements page for the latest information on system upgrades, new token listings, and trading rule changes. You can view real-time updates and official communiques on their platform.
